Description
Foreliggende oppfinnelse vedrører en anordning av den art som er beskrevet i innledningen til krav 1. The present invention relates to a device of the type described in the introduction to claim 1.
I en belegningsanordning hvor en bevegelig bane belegges på begge sider vil tilførselen av belegningsbestanddelen på banen generelt finne sted på den samme posisjon på begge sider av banen. Deretter beveges banen gjennom et utglatningsnipp hvor overskuddet av belegningsmiddel fjer-nes og belegningslaget utjevnes. I kjente belegningsanordninger vil det svært ofte oppstå brudd i banen, spesielt når banen som belegges er tynn og når banen belegges på en side med en tykk behandlingsbestanddel og på den annen side med en tynn behandlingsbestanddel. Banebrudd kan tilskrives to forskjellige forhold. For det første hvis behandlingsbestanddelen på den ene side er vesentlig tynnere enn behandlingsbestanddelen på den andre side vil banen ikke alltid bevege seg rettlinjet, men det vil genereres bølger i forskjellige steder som følge av forskjellig vis-kositet av behandlingsbestanddelene. Denne bølgebevegelse vil lett forårsake brudd av banen, spesielt ved høyere banehastigheter. For det andre når belegningsbestanddelen påføres banen på samme tid på begge sider vil væskebe-standdelen i belegningsbestanddelen samtidig absorberes i banen på begge sider og bruddstyrken for den våte bane er vesentlig lavere enn den for en tørr bane. In a coating device where a moving web is coated on both sides, the supply of the coating component on the web will generally take place at the same position on both sides of the web. The web is then moved through a smoothing nip, where the excess of coating agent is removed and the coating layer is levelled. In known coating devices, breaks in the web will very often occur, especially when the web being coated is thin and when the web is coated on one side with a thick treatment component and on the other side with a thin treatment component. Lane breaking can be attributed to two different conditions. Firstly, if the treatment component on one side is significantly thinner than the treatment component on the other side, the web will not always move in a straight line, but waves will be generated in different places as a result of different viscosities of the treatment components. This wave motion will easily cause web breakage, especially at higher web speeds. Secondly, when the coating component is applied to the web at the same time on both sides, the liquid component in the coating component will be simultaneously absorbed into the web on both sides and the breaking strength of the wet web is significantly lower than that of a dry web.
Hensikten med oppfinnelsen er å forbedre belegningsanord-ningens funksjon. Med dette menes at risikoen for banebrudd er liten selv ved høyere banehastighet. Oppfinnelsen har også til hensikt å forbedre belegningsanordningen beskrevet i tysk patentsøknad nr. P 34 07 225.1. The purpose of the invention is to improve the coating device's function. This means that the risk of track breakage is small even at higher track speeds. The invention also aims to improve the coating device described in German patent application No. P 34 07 225.1.
Særpreget ved foreliggende belegningsanordning er beskrevet i karakteristikken i foreliggende krav 1 i søknaden. En belegningsanordning konstruert i henhold til dette til-veiebringer hensikten med foreliggende oppfinnelse. Dette tilskrives i første rekke at på en side av banen påføres belegningsbestanddelen ved at denne fordeles på overflaten av en motvalse og ikke overføres til banen før selve ut glatningsnippet og for det andre fra det faktum at begge applikatorene er nær utjevningsnippet. Det tilsiktes at utspredningsposisjonene for belegningsbestanddelen og utjevningsnippet lokaliseres innen en 30 graders sektor på motvalsen, fortrinnsvis innen en sektor på 20 grader. The distinctive feature of the present coating device is described in the characteristic in present claim 1 of the application. A coating device constructed in accordance with this achieves the purpose of the present invention. This is primarily attributed to the fact that on one side of the web the coating component is applied by this being distributed on the surface of a counter roller and not transferred to the web until the smoothing tip itself and secondly from the fact that both applicators are close to the leveling tip. It is intended that the spreading positions for the coating component and the leveling tip are located within a 30 degree sector on the counter roll, preferably within a 20 degree sector.
I en foretrukket utførelsesform av oppfinnelsen er begge applikatorer av ekstruderingstypen som tilfører beleg-ningsmiddelet på de bevegelige overflater gjennom en spalte ved hjelp av et meget lite overtrykk. Det er viktig at applikatoren som tilfører belegningsbestanddelen på valsen er slik justert at mengden av tilført belegningsbestanddel ikke overskrider mengden av den nødvendige belegningsbestanddel så meget at det under utjevningsnippet danner seg en for stor dam som følge av banens høye oppad-rettede hastighet. In a preferred embodiment of the invention, both applicators are of the extrusion type which supplies the coating agent to the moving surfaces through a slit by means of a very small excess pressure. It is important that the applicator that supplies the coating component to the roller is adjusted so that the amount of added coating component does not exceed the amount of the required coating component so much that an excessively large pond forms under the leveling nip as a result of the high upward speed of the web.
Når belegningsbestanddelen er tilnærmet trykkløs i appli-katorenes munnstykker vil luft som følger med belegningsbestanddelen ikke dillatere da trykket forblir tilnærmet konstant og vil således ikke forårsake ubelagte områder på banen, hvilket ofte skjer med kjente belegningsanordninger, hvor bevegelsesretningen for banen er motsatt og hvor utjevningsnippet danner bunnslissen for oppdemningen av belegningsbestanddelen. I kjente belegningsanordninger er det en ytterligere ulempe at det hydrostatiske trykk i en slik oppdemming, som stiger i en bemerkelsesverdig grad fordi høyden av oppdemningens overflate må være tilstrek-kelig stor til å tillate et overskudd av belastningsmassen kan flyte bort fra endene av det dannede basseng. Som følge av disse lekkasjer er det ikke mulig å la kantsonene av banen være ubelagte, det er heller ikke mulig å anorde kontrollanordninger for bladene, munnstykkene etc. ved endeveggene, hvilket er mulig og foretrukket for belegningsanordningen i henhold til foreliggende oppfinnelse. When the coating component is almost depressurized in the nozzles of the applicators, air accompanying the coating component will not dilate as the pressure remains approximately constant and will thus not cause uncoated areas on the web, which often happens with known coating devices, where the direction of movement of the web is opposite and where the leveling tip forms the bottom slot for the damming of the coating component. In known coating devices, there is a further disadvantage that the hydrostatic pressure in such a dam, which rises to a remarkable degree because the height of the surface of the dam must be sufficiently large to allow an excess of the load mass to flow away from the ends of the pool formed . As a result of these leaks, it is not possible to leave the edge zones of the web uncoated, nor is it possible to arrange control devices for the blades, nozzles etc. at the end walls, which is possible and preferred for the coating device according to the present invention.
Å la kantsonene være ubelagt er nødvendig, eksempelvis når en side belegges med et overflatelim og den andre med et pigmentbelegg, eller når det er ønskelig å ha forskjellige Leaving the edge zones uncoated is necessary, for example when one side is coated with a surface adhesive and the other with a pigment coating, or when it is desirable to have different
flatevekter for beleggene på de forskjellige sider av banen, hvilket lettest kan utføres ved å forandre tørr-stoffinnholdet i belegningsbestanddelen, eller når det er ønskelig å la en side være fullstendig ubelagt. surface weights for the coatings on the different sides of the web, which can most easily be carried out by changing the dry matter content of the coating component, or when it is desired to leave one side completely uncoated.
Applikatoren lokalisert på den side av banen som vender mot utjevningsbladet eller lignende samvirker med en stiv støtte lokalisert på den motsatt side av banen. I en gun-stig utførelsesform er denne støtte et stivt utjevningsblad, hvis overflate er fremstilt av et plastmateriale med lav friksjonskoeffisient. I steden for et utjevningsblad kan det anvendes en motvalse eller lignende. Rommet som er nødvendig for støtten i retningen fra banen til motvalsen er liten og følgelig kan denne applikator plasseres nær utjevningsnippet. Banens bevegelsesretning er nedenifra og oppad, men det er ikke nødvendig at den er helt perpendikulær, i stedet kan den før utjevningsnippet avvike noe fra perpendikulær retning. Etter utjevningsnippet avviker banens bevegelsesretning fortrinnsvis klart fra retningen for en tangentlinje til motvalsen trukket gjennom utjevningsnippet. Når dette er tilfelle vil det dannes et bryt-ningspunkt ved utjevningsbladet eller lignende, hvilket forbedrer kvaliteten av belegget. Ved å anvende applikatoren på valsesiden av banen monterbar i en dreiet stilling kan belegningsanordningen i henhold til oppfinnelsen anvendes som belegningsanordningen beskrevet i den tid-ligere nevnte tyske patentsøknad. The applicator located on the side of the web facing the leveling blade or similar cooperates with a rigid support located on the opposite side of the web. In an advantageous embodiment, this support is a rigid leveling blade, the surface of which is produced from a plastic material with a low coefficient of friction. Instead of a leveling blade, a counter roller or similar can be used. The space required for the support in the direction from the web to the counter roll is small and consequently this applicator can be placed close to the leveling tip. The direction of movement of the track is from below upwards, but it is not necessary that it is completely perpendicular, instead it may deviate somewhat from the perpendicular direction before the leveling tip. After the leveling nip, the web's direction of movement preferably deviates clearly from the direction of a tangent line to the counterroll drawn through the leveling nip. When this is the case, a breaking point will be formed at the leveling blade or the like, which improves the quality of the coating. By using the applicator on the roller side of the web, mountable in a rotated position, the coating device according to the invention can be used as the coating device described in the previously mentioned German patent application.
Oppfinnelsen skal i det etterfølgende forklares mere nøy-aktig under henvisning til de vedlagte tegninger, hvor figurene 1 og 2 skjematisk viser sideriss av to forskjellige utførelsesformer av belegningsanordningen i henhold til foreliggende oppfinnelse. I tegningene indikerer tallet 1 den bevegelige bane, 10 et utjevningsblad og 9 en motvalse omfattende en motvalseaksel 15. Utjevningsbladet 10 kan erstattes med en utjevningsstav 10a. Utjevningsnippet 11 er seksjonen mellom motvalsen 9 og utjevningsbladet The invention will subsequently be explained more precisely with reference to the attached drawings, where figures 1 and 2 schematically show side views of two different embodiments of the coating device according to the present invention. In the drawings, the number 1 indicates the moving path, 10 a leveling blade and 9 a counter roller comprising a counter roller shaft 15. The leveling blade 10 can be replaced by a leveling rod 10a. The leveling tip 11 is the section between the counter roller 9 and the leveling blade
10 eller lignende montert på bladstøtten 18. På valsesiden 10 or similar mounted on the blade support 18. On the roller side
■ av banen er det en kileformet belegningsbestanddelappli- ■ of the track, there is a wedge-shaped coating component appli-
kator 2 som utsprer belegningsbestanddelen 16 på overflaten av motvalsen 9, hvorfra den tilføres banen 1 ved utjevningsnippet 11. På den motsatte side av banen 1 er det en tilsvarende applikator 4 som utsprer belegningsbestanddelen 16 direkte på banen. Belegningsbestanddelen 16, mas-se eller lim pumpes gjennom tilførselsrørledningene 7 og 8 til henholdsvis applikatorene 2 og 4, hvorfra den ekstru-deres fra munnstykkene i begge applikatorene 2 og 4 gjennom henholdsvis spaltene 3 og 5 til overflaten av banen eller på valsen 9. Applikatorene 2 og 4 er uavhengig monterbare og justerbare og er i en avstand på noen få mm fra påføringspunktet uten å berøre den bevegelige overflate, hvilket nedsetter faren for banebrudd. Avstanden fra spalten av munnstykket til banen 1 eller valsen 9 er passende når kun en liten mengde av belegningsbestanddelen 16 faller ned i oppsamlingstanken 13 under applikatorene 2 og 4. Belegningsbestanddelen 16 utspredes fra spalten 13 på valsen 9 og beveges med den roterende valse 9 mot utjevningsnippet 11, foran hvilket det vedhefter til banen 1 og hvor mengden av belegningsbestanddel 16 styres av trykket av cator 2 which spreads the coating component 16 on the surface of the counter roller 9, from where it is supplied to the web 1 at the leveling nip 11. On the opposite side of the web 1 there is a corresponding applicator 4 which spreads the coating component 16 directly onto the web. The coating component 16, paste or glue is pumped through the supply pipelines 7 and 8 to the applicators 2 and 4 respectively, from where it is extruded from the nozzles in both applicators 2 and 4 through the slits 3 and 5 respectively to the surface of the web or on the roller 9. The applicators 2 and 4 are independently mountable and adjustable and are at a distance of a few mm from the point of application without touching the moving surface, which reduces the risk of web breakage. The distance from the slot of the nozzle to the web 1 or the roller 9 is suitable when only a small amount of the coating component 16 falls into the collection tank 13 below the applicators 2 and 4. The coating component 16 is spread from the slot 13 of the roller 9 and moved with the rotating roller 9 towards the leveling tip 11, in front of which it adheres to the web 1 and where the amount of coating component 16 is controlled by the pressure of
utjevningsbladet 10 eller utjevningsstaven 10a. Mengden av belegningsbestanddel 16 tilbake på begge sider av banen 1 bestemmes av den samme innstilling av bladtrykket. Belegningsbestanddelen 16 som kommer fra spalten 5 i munnstykket fra applikatoren 4 presser banen 1 mot den stive støt-teplate 6 på motsatt side av banen, idet denne plate forhindrer en avbøyning av banen og overflaten av platen er fortrinnsvis belagt med plast for å gi den en meget glatt overflate. Støtteplaten 6 forhindrer samtidig at overskudd av belegningsbestanddelen 16, mellom valsen 9 og banen 1 avtatt ved utjevningsnippet 11, faller ned på banen 1 og i stedet fører massen til oppsamlingstanken 13. Tallet 17 indikerer skjematisk en vertikal bevegelig støtte for støtteplaten 6. the leveling blade 10 or the leveling rod 10a. The amount of coating component 16 left on both sides of the web 1 is determined by the same setting of the blade pressure. The coating component 16 coming from the gap 5 in the nozzle of the applicator 4 presses the web 1 against the rigid support plate 6 on the opposite side of the web, this plate preventing a deflection of the web and the surface of the plate is preferably coated with plastic to give it a very smooth surface. The support plate 6 simultaneously prevents excess coating component 16, between the roller 9 and the web 1 removed at the leveling tip 11, from falling onto the web 1 and instead leads the mass to the collection tank 13. The number 17 schematically indicates a vertical movable support for the support plate 6.
I en belegningsanordning hvor utjevningsnippet 11 og sen-terpunktet for motvalsen 9 er i det samme horisontale plan vil tangentlinjen 14 til motvalsen trukket gjennom utjevningsnippet 11 være perpendikulær. Retningen for banen 1 3 In a coating device where the leveling tip 11 and the center point of the counter roller 9 are in the same horizontal plane, the tangent line 14 to the counter roller drawn through the leveling tip 11 will be perpendicular. The direction of the trajectory 1 3
under utjevningsnippet avviker ikke mere enn 5 grader fra tangentlinjens retning og fortrinnsvis bort fra valsen 9. Etter utjevningsnippet 11 avbøyes banen 1 i retning bort fra valsen 9, fortrinnsvis 3-5 grader og ikke overstigende 7 grader. Denne retningsforandring av banen 1 påvirker fordelaktig fordelingen av overflatelaget inn mot overflaten av valsen 9 og inn i den del som forblir tilbake på overflaten av banen 1, slik at overflaten tilbake på banen 1 blir glattere enn hvis banen 1 skulle bevege seg i retningen for tangentlinjen 14 for motvalsen 9. during the leveling nip does not deviate more than 5 degrees from the direction of the tangent line and preferably away from the roller 9. After the leveling nip 11, the path 1 is deflected in the direction away from the roller 9, preferably 3-5 degrees and not exceeding 7 degrees. This change in direction of the path 1 advantageously affects the distribution of the surface layer towards the surface of the roller 9 and into the part that remains back on the surface of the path 1, so that the surface back on the path 1 becomes smoother than if the path 1 were to move in the direction of the tangent line 14 for the counter roller 9.
Som følge av deres kileformede konstruksjon kan munnstykkene i applikatorene 2 og 4 bringes meget nær utjevningsnippet 11. Avstanden mellom utjevningsnippet 11 til spaltene 3 og 5 i de nevnte munnstykket kan være 100 mm eller mindre. I praksis er denne avstand avhengig av diameteren av motvalsen 9. I en belegningsanordning i henhold til oppfinnelsen tilstrebes det at en vinkel for en sektor av motvalsen avgrenset av linjene 12a og 12b som går henholdsvis gjennom utjevningsnippet 11 og utspredningspunk-tet 3 ikke er mer enn 30 grader og fortrinnsvis ikke mer enn 20 grader. As a result of their wedge-shaped construction, the nozzles in the applicators 2 and 4 can be brought very close to the leveling tip 11. The distance between the leveling tip 11 to the slots 3 and 5 in the said nozzle can be 100 mm or less. In practice, this distance depends on the diameter of the counter roller 9. In a coating device according to the invention, it is sought that an angle for a sector of the counter roller bounded by the lines 12a and 12b which pass respectively through the leveling tip 11 and the spreading point 3 is no more than 30 degrees and preferably no more than 20 degrees.
I fig. 2 er vist en alternativ måte å anvende belegningsanordningen i henhold til oppfinnelsen. Munnstykket 2 er montert i en dreiet posisjon, slik at spaltene 3 og 5 av henholdsvis munnstykkene 2 og 4 er motstående hverandre på hver side av banen. For dette må støtteplaten 6 senkes til posisjonen 6a. Også i denne tilstand fungerer belegningsanordningen meget godt. In fig. 2 shows an alternative way of using the coating device according to the invention. The nozzle 2 is mounted in a rotated position, so that the slots 3 and 5 of respectively the nozzles 2 and 4 are opposite each other on each side of the track. For this, the support plate 6 must be lowered to position 6a. Even in this condition, the coating device works very well.
